The integration with the Interactivity API for the Add To Cart is great, but it's also needed in the product page. Currently, when shoppers click on add to cart in the product page, the page reloads with a message that the product has been added to the cart. I'm currently using an AJAX plugin to avoid this and prevent the page from reloading when adding to the cart. Also, this enables the mini cart to auto open on add to cart.
